Application filed April 29, 1807. Serial No. 370,865.

' State of Michigan, have invented certain new and useful Improvementsin Adjustable FNeb- Guides; and I. hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, which form part of this specification.

This invention is an improvement in folding mechanisms, for web printingpresses, and has particular reference to the web-guide roller which isusually located between the first-fold rolls, at the apex of the former,and the cutting cylinder or second-fold devices.

The object of the invention is to mount said roller in such manner thateither end or both ends, of such roller can be adjusted both verticallyand horizontally so that the said roller may be given any desiredposition out of true parallelism with the folding rolls or cuttingcylinders as may be found necessary to prevent crawling, cracking andslipping of the web after leaving the first-fold rol.s.

A great deal of trouble is experienced by pressmen in getting the web torun properly from the former to the cutting cylinders so that the lattercan operate accurately. If the web is drawn too tightly over the apex ofthe former it is liable to be cracked or ruptured, and as the thicknessof webs increases it becomes more difficult to get the web run ningtruly to the cutting cylinders and second fold rolls. I have discoveredthat if the guide-roller, under which the fold ed webs are turned afterleaving the first-fold rolls, is made adjustable, so that it can beadjusted laterally or horizontally to any desired inclination, thedifliculties in handling the folded Web and various thicknesses of websin the folder can be overcome by properly ad'- justing thisguide-roller.

The present invention therefore consists in the novel mounting of suchguide-roller, and will be fully understood from the followingdescription in connection with the accompanying drawings in Which Figure1 1s a detail side View of a folding mechanism showing the adjustableguideroller supports in elevation. Fig. 2 is a front view of Fig. 1, theframe being removed and certain parts being in section.

1 designates a former over which the Web to is led from the printingmechanism; (not shown) at the 2. ex of the former are located thefirst-fold rolls 2 as usual. From the rolls 2 the web is passed under aguide-roller 3 and then assed customarily between the cutting cylin ersl, by which the web is drawn past the roll 3 and fed forward over thesecondfold rolls 5 which latter are usually arranged at right angles tocutting cylinders 4. The

severed sheets are tucked between rolls 5 by a' blade 5*. The aforesaidparts and the arrangement thereof are well known, and

therefore they are simply diagrammatically illustrated in the drawings.

The guide-roller 3 is provided. with trunnions 3 which are journaled incastings 6 which are attached to upstanding arms 7 on castings 7 bymeans of bolts 6* tapped into arms 7 and passing through slots 6* incastings6. A double threaded bolt 6 is tapped into the lower end of eachcasting 6 and into the upper side of the related casting 7, and bvturning bolt 6, after bolt 6' is loosened,

the related casting 6 can be adjusted vertically' on arm 1 and may berigidly secured when properly adjusted byLtightening bolt 6.

The castings 7 are loosely mounted on a shaft 9 a which is supported inthe main frames of the folder, and is he t from rotation by a key 9 orother suitable means. The cas ings 7 are kept from longitudinal movementon the shaft 9 by means of collars 9 and bifurcated castings 8, saidcollars 9 and castings 8 being. securely pinned or fixed on theshaft 9*,as shown.

Each casting 8 is provided with opposite depending arms 8 which extendbelow shaft 9 and on opposite sides of a finger 7 depending from theadjacent casting 7, and through the ends of arms 8 are ta ped bolts 8which contactwith opposite si( es of said linger 7 c and thereby keepcastings 7from swinging or turning upon shaft 9; but by loosening onebolt 8 other, the casting 7 can be rotatablyadjusted on theshaft 9 Thuseach casting 6, and

the adjacent end of the roll 3, can be horizon-.

tally adjusted right or left and firmly held in any adjusted position.

As each end of the guide roller 3 is suported by similar devices uponthe shaft 9 it is obvious that either end of such roller can be adjustedvertically and horizontally, and each end of the'roller 3 may beadjusted similarly to or differently from, the other end, so that theroller can be given any position deand tightening the sired relativelyto the rolls 2 and 4,-and thus undue strain or tension on either edge ofthe Web can-be easily prevented.

While I have illustrated cylinders 4 as cutting cylinders, they also actto feed the paper forward to the second foldin devices, and plain feedrolls or cylinders might be used in some makes of folding mechanisms inlieu of or in addition to the cutting cylinders 4; and in some foldingdevices the second fo1d-rolls are parallel with the cutting cylinders orfeeding rolls, therefore I do not web to be restricted to the particulararrangement of cutting cylinders and second-fold rolls shown in thedrawings for, as before stated, the drawings merely illustrate one kindof known folding mechanism to which the invention is apphoable. i

In any folding mechanism to which the invention is applied, the Web canbe adjusted vby this roller 3 so that the variations caused bydifferences in humber of webs folded can be easily compensated for; andso that the cutting cylinders will cut the margins.

Having thus described. my invention what I claim as new and desire tosecure by Letters Patent is: I

1, In combination with folding mecha nism, a Web guiding rollerinterposed between the first-fold rolls and second-fold rolls, and meansfor adjusting either end of said roller independently of the otherend'both horizontally and vertically in different de rees.

2. In a foldi mechanism, the com ination of the firstold rolls, cuttingcylinders, and avweb uide roller interposed between the rolls andcylinders; with means for vertically and horizontally adjusting eitherend of said web guide roller in different degrees independently of itsother end.

3. In comoination a Web guide roller, ver tically adjustable castingssupportin said roller, horizoritall adjustable pivoted castinigs,supporting t e first castings; means for a justing the first castingsupon the second, and means for adjusting the second castings on theirpivots.

4. The combination of a support, castings pivotally mounted thereon,castings fixed properly between I beside the first castings, boltstapped through vertically admstable castings mounted on the firstcastings, and a guiderollerjoun naled in the vertically adjustablecastin s.

6.111 a folder, the combination of toiling rolls, and cutting cylinders,and a guide roller located between t cylinde'rs';' with a shaft, a pairof pivo castings provided with upstanding, arms and depen ing fingers,cast s fixed beside the first castings and rovide with arms extending onop osite si es of the fin ers of the first castings, olts tapped throughthe cas'ti' s and contacting with op osite sides of said fingers; andvertically a justable bearings for the guide roller shaft attached .tothe arms of the first castings.

7. The combination of a former, folding rolls, cutting cylinders, secondfold-devices; and a web uide roller located between the first fold rollsand the cutting c linders; with a shaft, a pair of castings loose y hungthereon provided with upstanding arms and deending fingers, castingsfixed on the shaft beside the rst castings and provided with armsextending on opposite sides of the fingers of the first castings, boltstapped through the arms of the castings and contacting with oppositesides of said fingers, and vertically ad ustable castin s attac ed tothe arms of the first castings by slots and bolts, and pro vided withbearings for the guide roller shaft,

substantially as described.

7 In testimony that I claim the foregoing as my own, I aflix mysignature in presence of two witnesses. v
